Inspection of low-pressure storage tank Butt-weldsComplete penetration and complete fusion is required (to the degree mandated by the acceptance criteria for examination method utilized) for welds joining tank wall plates to API Std 650 stainless and carbon steel tank tank wall plates. Examination for quality of welds shall be made using either the radiographic method specified in API 620 standard 7.15.1 and applied in 7.17, or alternatively, by agreement between the Purchaser and the Manufacturer, using the ultrasonic method specified in 7.15.3.1. In addition to the radiographic or ultrasonic examination, these welds shall also be visually examined as specified in 7.15.5. Furthermore, the Purchaser’s inspector may visually inspect all butt-welds for cracks, arc strikes, excessive undercuts, surface porosity, incomplete fusion, and other defects.
The main reason of "small breathing" loss of API Std 650 stainless and carbon steel tank is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API Std 650 stainless and carbon steel tank also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API Std 650 stainless and carbon steel tank is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.
